HEAT TRANSFER AND THERMODYNAMICS
HT34 Jacketed Vessel with Coil & Stirrer - Issue 1
Vessel Heating or cooling of a process liquid in a tank, either batchwise or with continuous product feed, is common practice throughout industry.
The characteristics of the heat transfer using an external jacket or internal coil can be demonstrated together with the effect of stirring the vessel contents.
Ordering Specification
Miniature jacketed vessel heat exchanger system for use with an Armfield
Heat Exchanger Service unit
Comprises processing vessel with outer jacket, inner coil, variable speed
stirrer and baffle.
K-Type thermocouples measure the vessel contents and the inlet and outlet
temperature of both fluid streams (6 in total).
The Heat Exchanger is designed to be installed on the service unit without
the need for tools.
A comprehensive instruction manual describing how to carry out the laboratory
teaching exercises in combined radiation and convection (free and forced)
and their analysis as well as assembly, installation and commissioning is
included.
Technical Details
The accessory consists of a jacketed vessel with the following features:
- The vessel consists of a stainless steel wall with PVC base and clear acrylic top. A glass outer jacket allows the wall of the vessel to be surrounded with hot fluid for indirect heating from the outside. Alternatively, a stainless steel coil inside the vessel allows the cold fluid contained within the vessel to be indirectly heated from inside.
-The vessel incorporates a variable speed stirrer and baffle arrangement to allow thorough mixing of the vessel contents when required.
-An adjustable overflow allows the volume of liquid inside the vessel to be varied with a maximum capacity of 2 litres and a minimum of 1 litre.
-The vessel can be operated batchwise by simply filling to the overflow or with continuous feed of cold liquid to the base of the vessel, the excess liquid flowing from the overflow to drain.
Temperatures are measured using type K thermocouples with miniature plug for direct connection to the electrical console on HT30X. Thermocouples are installed at the following six locations:
- Thermocouples are installed at the following six locations:
• Vessel contents (cold fluid)
• Hot fluid inlet to jacket
• Hot fluid outlet from jacket
• Hot fluid inlet to coil
• Hot fluid outlet from coil
• Cold fluid inlet to vessel
• Quick release hot and cold fluid connections allow rapid connection
to HT30X and conversion from heating jacket to heating coil.
